(a) Assemble the valve body in the uppermost position.
NOTE: When the brakes are applied, the piston will move down about 0.8 mm (0.03 inch). Even at this time, the piston should not make
contact with or move the load sensing spring.
(b) In this position, check the rear brake pressure.
-
With the front pressure @ 1,960 kPa (285 psi) the rear pressure should be 1,960 kPa (285 psi).
-
With the front pressure @ 3,920 kPa (570 psi) the rear pressure should be 2,352 kPa ± 196 (342 ± 28.5 psi).
-
With the front pressure @ 6,860 kPa (997.5 psi) the rear pressure should be 2,940 kPa ± 343 (427.5 ± 50 psi).
NOTE: If the measured value is not within standard, replace the valve body.
